According to the Hon'ble High Court of Sikkim Judgement dated 26th May, 2015 in WP(c) 4/2013 and dated 29th5999843_SikkimHighCourtJudgement_on_student_vs_SMU.pdf
May, 2015 in WP(c) 8/2015, it is clearly mentioned that the University got 3 years recognition from 2009-10 to 2011-12. The recognition of the university was expiring on 14.10.2012. Before that they have already applied for renewal. But after 25.10.2012 Sikkim High Court freeze the fresh admission.
In its Judgment High court also said that degrees of the candidates who had got admission and completed their distance courses anytime prior to the academic session 2011-12 or the Students who started their distance course prior to the session 2011-12 but completed the course afterwards is valid.
Further, Students who were admitted to the programmes from February 22, 2013, to June 26, 2015 (Stay period granted by Sikkim High Court) their degrees are also valid.
So, it is to say that status of any admission between October 25, 2012 and February 22, 2013, is still unclear.
As you have get admission in the course from from August 2012 that is before the expiry of the recognition of the University. So your degree might be valid.
